摘要： Communication methods, in a distributed antenna system that includes a head end unit for communicating channelized digital baseband signals with remotely located units, are provided. The channelized digital baseband signals include call information for wireless communication. The head end unit includes a channelizer section and a transport section. The channelizer section can extract, per channel, the channelized digital baseband signals using channel filters and digital down-converters. The transport section can format the channelized digital baseband signals for transport together using a transport schedule unit for packetizing and packet scheduling the channelized digital baseband signals. A signal processing subsystem can control a gain of uplink digital baseband signals, independently, that are received from the remotely located units prior to summing the uplink digital baseband signals.

摘要： The invention relates to a method for transmitting data between a first unit which accumulates data that has been generated with a first frequency and a second unit which requests the accumulated data with a second frequency. The method has the steps of requesting a first total increment and a first value, which represents a time increment belonging to the first total increment, from the first unit, said first total increment being the data content of the accumulated data block provided at the request time in the first unit; generating a second total increment from the first total increment using the first value, the second total increment being the data content of a data block adapted to a nominal time increment of the second frequency; and transmitting the second total increment to the second unit.

摘要： A method and apparatus for maintaining data throughput in a data element includes receiving a clock and a first plurality of instances of data having a first width on an input, sampling consecutive ones of instances of the data having the first width at consecutive ones of a first rising edge and a first falling edge of the clock, respectively, to generate two plurality of instances of sampled data having a first width. The plurality of instances of sampled data is then sampled at a second rising edge of the clock and parallelized to generate a second plurality of instances of parallel data having a second width greater than the first width. The parallel data may then be processed to for example generate statistics to monitor link integrity, prior to being transmitted. A 10 Gbps data transmission speed may be maintained using the IEEE 802.3ae-specified media independent interface clock.

摘要： A circuit arrangement and technique are provided for passing N-bit digital data using an M-bit datapath, M being less than N. A plurality of N-bit words is arranged for transfer in two portions. A first portion of each of the plurality of words is transferred in M-bit groups. At least one other bit group is transferred, including bits from the second portions of at least two of the plurality of words. After transfer, each first portion is reassembled with a corresponding second portion into respective N-bit words. The digital data is arranged for transfer at one rate, and transferred at a second rate at least as fast as the first rate. In one embodiment, X words of data are transferred from one storage element while another X words are arranged for transfer in another storage element. In a more particular embodiment, 10-bit data is passed over a standard 8-bit digital visual interface.

摘要： There are disclosed a transmission rate matching apparatus and a method thereof for a next generation mobile communication system. In the conventional technology, when data bit is transmitted from a terminal to a base station, it is transmitted by radio frames, each column of a block interleaver includes biased data bit. Accordingly, in order to solve above-mentioned problem, the transmission rate matching apparatus for the next generation mobile communication system in accordance with the present invention comprises an encoder for performing error-correction-encoding of an input bit column, and generating a code word bit from the error-correction-encoded input bit column, a block interleaver for being inputted the code word bit, storing it as row unit, and outputting it as column unit, a switching unit for performing a switching algorithm for converting an output sequence of the code word bit crossly and outputting them to the block interleaver in order to distribute the biased data bits included in the each column of the block interleaver uniformly when the number of the code word bit of the encoder and the number of the column of the block interleaver are not coprime, a radio frame segment processing unit for generating a radio frame after being inputted the column unit data outputted from the block interleaver, and a transmission rate matching unit for matching the data bits included in the radio frame to a transmission format suitable for a transmission between a terminal and a base station, and transmitting it.
